TRANSFER SHEET.

Application filed December 11, 1925. Serial No. 74,771.

This invention relates to a process for making transfer sheets and an'ink for use in the process.

Heretofore transfer sheets have been made by a process which included anink which by reason of its character had to be kept quite a little abovethe ordinar temperature in order to work properly. ith such an ink andwith the usual processes a comparatively small number of transfer sheetsmay be formed per hour, consequently they are com aratively costleretofore the dlfiiculties of the process wherein the ink must be warmedhave been sought to be overcome, but in so doing resort has been had tosuch coloring matters as aniline dyes, which. when transferred on tosuch material as silk become indelible and cannot be washed out.

Applicant has as an object a process and an ink therefor by whichtransfer sheets may be printed cold and the transfer made on to thematerial is fugitive, when washed as in ordinary practice. I

In describing the invention in detail and a particular product made bythe use of the process, reference is had to the accompanymg drawing,wherein I have illustrated a particular product and wherein likecharacters of reference designate corresponding parts throughouttheseveral views, and in which:

Figure 1, illustrates a transfer sheet with a design in the plurality ofcolors thereon; Fig. 2, illustrates a transfer sheet with a design inone color thereon.

In order to car out the process applicant has devised a printingcomposition, called an ink.

The ink used by applicant is made preferably in the following manner.

Ordinary rosin of commerce is heated in any suitable or appropriate wayuntil it .will flow freely. n a separate rece tacle mineral parafiine,the ordinary para e of commerce, is heated, until it will flow freely.The two, rosin and parafiine, are then mixed, pouring one into theother, with constant stirring. In addition to the rosin and parafline,cocoa butter and mutton tallow are melted together in a receptacle untilthey will flow freely and are then mixed with the mixed rosin andparaifine by pouring therein with constant stirring.

The mixture resulting from the above described operations is then groundeither by hand or in some such device as a suitable type of power paintmill and to it is added preferably as the grinding proceeds, suchguantity of coloring matter as will give the esired color and shade tothe transfer design then impressed to the desired material. a Thecoloring matter used by applicant is a most important element of theinvention. Applicant has found that for his purposes a mineral coloringmatter is most appropriate, because the composition of his ink is suchthat although the ordinary handling of his transfer sheets when dry willnot smudge the design, nevertheless, a vi orous washing of the materialto which the esign .is transferred will remove. the ink from thematerial. Applicant has found that if a mineral coloring matter, thatis, one which does not combine with the material, to in effect d e it,is used it being merely held mechanically by the mk on the material, itis also removed, by washing, so that it is fu 'tive.

fter properly grindin the mixture, I adjust the viscosity so t at itwill work properly with the particular type of ress and ink rollersused. I .do this by a ding rosin made fluid by heat until by trial Ireach the exact viscosity desired.

The quantities used in making my ink are about as follows Mutton tallow,1 oz.; cocoa butter, 1 oz.; parafine,-4 oz-; rosin, 6 oz.; additionalrosin, a suflicient quantity; mineral pigment, a sufficient quantity.

Any desired mmeral pigment may be used that will give the desired color.

If what is technically known as offsettin occurs the quantity of rosinmay be slig tly increased, and in general the vis-' cosity of the inkwill be regulated by the type of roller present on the press upon whichthe ink is used.

The ink made as hereinbefore described is usable upon ordinary platepresses. The ink bein used to fill the usual font and theprintmg of thetransfer sheets being accomplished as ordinary printing. I

In Fig. 1 I have illustrated a five'pointed star on a sheet 1. Thepoints 2 and 3 of the star are colored respectively, yellow and blue. InFig. 2, I have illustrated a five pointed star in outline on sheet 4 thebounding lines all being in one color, preferably blue. For the yellow Ipreferably use chrome yellow and for blue, ultramarine.

drying, in reverse on the material to which the design is to he appliedand a hot roller for that reason are used in the composition.

or sad} iron is applied thereto, whereupon the design Will betransferred to the material reproducing the color or colors on thetransfer sheet.

Cocoa butter and mutton tallow have properties not possessed by rosinand paraf fine in that they stay moist much longer and This property ofthe cocoa butter and mutton tallow causes the transfer design to loosenup more readily during the transfer and gives quicker fluidity. Theseproperties could not be obtained by the useiof rosin and parafiine.

Although I have particularly described my process and products resultingfrom my process, nevertheless, I desire to have it In use the transfersheet is applied, after'f'understood that the forms selected are merelyillustrative but do hot exhaust the possible expresions of the idea ofmeans underlying my invention.

What I claim as new and desire to secure -hy Letters of Patent of theUnited States:

1. An ink for printing transfer sheetsconsisting'of, cocoa butter,mutton tallow, parafline, rosin and a mineral pigment proportioned togive a printing viscosity at ordinary temperature.

2. An ink for printing transfer sheets consisting of and in proportionsas follows, cocoa butter one ounce, mutton tallow one ounce, parafiinefour ounces, rosin six ounces, mineral pigment, a suflicient quantity,together with suflicient additional rosin as to give printing viscosityat ordinary temperature.
